try hooking up a fuel pressure test gauge to fuel rail pre filter and post filter and rev truck to 2500 rpm what is fuel pressure ?
next using a vacume pump attach to fuel pressure regulator pump up while engine is running only pump up to 8 psi to see if pressure changes if not replace pressure regulator .
it could also be ur speed sensor switch on overdrive transmission
good luck with it

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

Do you have the fuel tester hooked the in the overgrown air valve on the fuel rail in the back of the engine? Or do you have the fuel line unhooked in the back and hooked to the pressure pump? You want the fuel pressure to be in that 60 lb range so if you are hooked into the pressure valve on the fuel rail allowing fuel to go through, then I am betting it is the fuel pressure regulator. To get to that, you have to take the throttle body off and take the plastic plenum that covers the injector packs. On the back of the mount where your six pack of injectors are sits the pressure regulator. If it is faulty then it is dumping fuel instead of holding the pressure like it should.
Get a Chilton or Clymer manual and it shows you in pretty good detail how to fix it. I've done it to my 98 S10 with the same engine.
If you unhooked the fuel line so you are losing pressure from the line back to the pump then I would say your pump is letting fuel back to the tank when it shuts off. My money is on the first possibility though.

U 1st need to test fuel pressure at the fuel pressure test port on the top of the engione in the fuel supply rail to the injector tops, it looks like a metal tire vale stem, u will need to buy a special fuel pressure tester to do this test. U should have around 55-60 PSI at idle, it should go up when u gun the engine but never go down, if it goes down the fuel filter or pump are suspect.
